SIGNALISATION DE RÉFÉRENCE DE POSITIONNEMENT BASÉE SUR LA LIAISON MONTANTE DANS DES SYSTÈMES À FAISCEAUX MULTIPLES

摘要

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify a beam correspondence between a set of synchronization signals transmitted by a base station and an uplink positioning reference signal. The UE may receive a synchronization signal from a base station and determine a transmit beam for the UE to use to transmit the uplink positioning reference signal based on the received synchronization signal and the identified beam correspondence. The UE may then transmit the uplink positioning reference signal using the determined transmit beam. A base station may identify a beam correspondence between a set of synchronization signals and an uplink positioning reference signal, and transmit an indication of the beam correspondence. The base station may then receive the uplink positioning reference signal from a UE based on the transmitted indication of the beam correspondence.
